Patent number: 11230799Abstract: An artificial turf mat includes a backing and a number of protruding artificial grass blades divided into rows and connected thereto. The mutual distance between successive blades in a row is substantially equal to the distance between adjacent rows and amounts to at least 10 mm. Such an artificial turf mat can be used to form artificial turf fields, for example, on which sports, and in particular ball sports, are played.Type: GrantFiled: February 9, 2017Date of Patent: January 25, 2022Assignee: Greenfields B.V.Inventor: Hugo de Vries

Patent number: 10221512Abstract: Primary and secondary feeders, such as creels or beam systems can be employed to provide increased efficiency in swapping out yarns, particularly with solution dyed yarns to create finished carpets. A secondary feeder might be replaced with another to relatively quickly provide a different color palate without a need to change much, if anything, with regard to the primary feeder.Type: GrantFiled: August 12, 2016Date of Patent: March 5, 2019Inventor: Robert S. Weiner

Patent number: 10125441Abstract: A method of tufting carpet using multiple yarns directed through at least one single needle, if not a plurality of such situations, whereby the needles tuft a carpet having unique specifications. Specifically, the yarns are pre-twisted together, and can be solution dyed and/or of have different twist characteristics, such as selected from the group of high twist, standard twist, low twist, no twist, flat yarns and/or pre-twisted flat yarns.Type: GrantFiled: April 26, 2016Date of Patent: November 13, 2018Inventor: Robert S. Weiner

Patent number: 9974424Abstract: A laminate cleaning implement with a facing sheet, a substrate, and optionally a backing sheet. The facing sheet, the substrate, and the optional backing sheet are mechanically intermeshed. The mechanically intermeshing can provide one or more discrete tufts protruding outwardly from the laminate.Type: GrantFiled: June 18, 2014Date of Patent: May 22, 2018Assignee: The Procter & Gamble CompanyInventors: Donald Carroll Roe, Jill Marlene Orr, John Joseph Curro

Patent number: 6926044Abstract: A method for making a fabric having a ground and pile threads inserted between the ground threads is provided. The method comprises a step of weaving two fabrics simultaneously so that the fabrics are positioned parallel and spaced by a predetermined distance, and the pile threads are inserted alternately between the ground threads of one fabric and between those of the other fabric. Also, each pile thread is wound around one of the ground threads by one or more turns. The method further comprises cutting the pile threads between the fabrics, and heat setting the fabrics to bind the pile threads to the ground firmly. The pile threads are made of acrylic yarn, and the weight percentage of the pile threads in the fabric is between 80 and ninety-five 95, and the weight percentage of the ground threads in the fabric is the remainder.Type: GrantFiled: November 1, 2004Date of Patent: August 9, 2005Inventors: William B. Kim, Charles S. Kim

Patent number: 6457490Abstract: A method for manufacturing a loop pile fabric with a varied appearance includes a woven backing fabric. Loop weft yarns (12A), (12B) are provided outside the backing fabric, and loop warp yarns (1), (2), (3) are so provided that they are alternately inwoven in the backing fabric and form a pile loop (13), (14) over at least one loop weft yarn (12A), (12B), and the loop weft yarns (12A), (12B) are subsequently removed. By providing first (12A) and second loop weft yarns (12B) with a different thickness, pile loops (13), (14) of different height are formed. To obtain a fabric in which both pile loops (13) and cut pile (15) occur subsequently a top part can be removed from a number of pile loops (13). In areas (19) where no pile loops are formed effect backing weft yarns (11B) with laterally protruding filaments can be inwoven in the backing fabric. A loop pile fabric can be manufactured according to this method.Type: GrantFiled: February 15, 2001Date of Patent: October 1, 2002Assignee: N.V.

Patent number: 6367514Abstract: A fabric with a rib structure, in particular a false boucle carpet, with cut pile (13) and/or pile loops (12) is formed by a method for weaving such a fabric. On a weaving machine, such as a rod weaving machine, a backing fabric is woven by bringing weft yarns (1), (2), (3) between warp yarns (4-9) in successive weft insertion cycles, alternately weaving in warp yarns (7), (8) in the backing fabric and rib-formingly passing them around over at least one weft yarn (3). In a number of weft insertion cycles a loop-forming element (10), such as for example a wire or a wire with a blade, is provided above the backing fabric and at least one pile warp yarn (7), (8) is loop-formingly passed around over this loop-forming element (10). This method enables weaving of a fabric with a very varied appearance, because apart from the false boucle effect, areas with pile loops (12) and/or areas with cut pile (13) can also be obtained.Type: GrantFiled: July 25, 2000Date of Patent: April 9, 2002Assignee: N.V. Michel Van de WieleInventor: Stefaan Demey

Patent number: 6247506Abstract: Method for manufacturing a fabric with a rib structure, in particular a false bouclé fabric, whereby a backing fabric is woven out of binding warp threads (7), (8) and weft threads (1), (2), whereby pattern warp threads (5), (6) are alternately interlaced in the backing fabric and along one side of the backing fabric are rib-formingly passed around at least one weft thread (3) running outside the backing fabric. A fabric is thus obtained with a rib structure on only one side. Because of this the consumption of pattern warp yarn can be reduced.Type: GrantFiled: November 8, 1999Date of Patent: June 19, 2001Assignee: N.V. Michel Van de WieleInventors: Johnny Debaes, Ludo Smissaert, Nico Vandoorne

Patent number: 5771943Abstract: A carpet includes a weft fill material (18c) which fills the loops formed in the pile of warp yarns (14a and 14b) so as to be partially visible to contribute to both the design and appearance of the resultant carpet and the durability by supporting the inside of the loops formed by the warp yarns (14a and 14b). The binding chains (17a and 17b), with the wefts (18a and 18b), bind the pile warp yarns (14a and 14b) to the carpet backing with the stuffer (16) being held securely between the wefts (18a and 18b) . In alternative embodiments the binding chains (17a and 17b) can be partially or totally omitted with the warp yarns (14a and 14b) being fed over and under the stuffer (16). Apparatus for forming the carpet is described.Type: GrantFiled: June 21, 1995Date of Patent: June 30, 1998Assignee: Duralite Carpet Corporation LimitedInventor: Brian Carlson
